Abstract

The invention concerns a switchgear, such as a change-over switch, with very good quality/price ratio, enabling new switching combinations and simple and inexpensive production of different types of switchgear. The switchgear (1) comprises two superposed switching blocks (10, 20) each associated with an actuating block (30, 40) and a control block (60) provided with a control shaft (64) connected to a handle (61) for simultaneously controlling said actuating blocks (30, 40). This switchgear (1) is characterised in that the actuating blocks (30, 40) are superposed back to back and are arranged between the mutually inverted switching blocks (10, 20). The actuating blocks (30, 40) comprise a mechanism with modifiable configuration. Likewise, the connection points between this mechanism and the control shaft (64) can also be modified, thus resulting in five switching combinations between the switching blocks. The invention is applicable to electrical installations in general.

La présente invention concerne un appareil de coupure tel qu'un commutateur- inverseur pour une installation électrique, cet appareil comportant au moins deux blocs de coupure superposés, chaque bloc de coupure comportant au moins deux paires de bornes destinées à être raccordées à au moins deux phases de ladite installation, au moins deux paires de contacts fixes couplées auxdites bornes et au moins deux contacts mobiles à deux positions stables, une position fermée dans laquelle chaque contact mobile relie les contacts fixes d'une même paire pour établir le passage du courant électrique et une position ouverte dans laquelle chaque contact mobile sépare lesdits contacts fixes pour interrompre le passage dudit courant électrique, les contacts mobiles étant montés sur un barreau mobile commun agencé pour se déplacer en translation, ledit appareil comportant également au moins deux blocs d'actionnement, chacun étant agencé pour déplacer ledit barreau mobile du bloc de coupure correspondant, et un bloc de commande pourvu d'un arbre de commande pouvant être couplé à une poignée et agencé pour commander simultanément lesdits blocs d'actionnement.The present invention relates to a switching device such as a change-over switch for an electrical installation, this device comprising at least two superimposed switching blocks, each switching block comprising at least two pairs of terminals intended to be connected to at least two phases of said installation, at least two pairs of fixed contacts coupled to said terminals and at least two movable contacts with two stable positions, a closed position in which each movable contact connects the fixed contacts of the same pair to establish the passage of electric current and an open position in which each movable contact separates said fixed contacts to interrupt the passage of said electric current, the movable contacts being mounted on a common movable bar arranged to move in translation, said device also comprising at least two actuation blocks, each being arranged to move said movable bar of the blo c corresponding cutoff, and a control block provided with a control shaft which can be coupled to a handle and arranged to simultaneously control said actuation blocks.
De tels appareils de coupure sont généralement utilisés pour la distribution électrique à basse tension monophasée, triphasée ou tétraphasée, l'intensité allant de quelques dizaines à plusieurs centaines d'Ampères, us assurent la commutation, l'inversion de source ou la permutation en charge de deux circuits de puissance basse tension ainsi que leur sectionnement de sécurité. Pour obtenir un appareil de coupure équivalent à un commutateur-inverseur, on superpose de manière connue deux interrupteurs standards placés dans le même sens, chacun étant composé d'un bloc de coupure, de son bloc d'actionnement et de son bloc de commande, ce qui nécessite d'avoir la totalité des pièces en double exemplaire. Puis on couple la poignée de commande de l'interrupteur supérieur aux deux blocs d'actionnement en rallongeant l'arbre de commande dudit bloc de commande par une rallonge d'arbre spécifique, les points d'attache des bielles prévues dans les blocs d'actionnement étant modifiés sur l'arbre de commande. La poignée peut avoir trois positions stables, une position médiane "0" et deux positions "I", "LT" de part et d'autre de la position médiane, par exemple à - 65° et à + 65°. Les commutateur-inverseurs de ce type ne permettent d'obtenir que deux seules combinaisons de commutation : dans la première combinaison, l'un des interrupteurs est fermé quand l'autre est ouvert et, en position médiane, les deux interrupteurs sont ouverts. Dans la seconde combinaison, l'un des interrupteurs est fermé quand l'autre est ouvert et, en position médiane, les deux interrupteurs sont fermés simultanément.Such breaking devices are generally used for low-voltage electrical distribution, single-phase, three-phase or four-phase, the intensity ranging from a few tens to several hundred amperes, they ensure switching, source reversal or permutation under load. two low voltage power circuits and their safety disconnection. In order to obtain a cut-off device equivalent to a change-over switch, two standard switches placed in the same direction are superimposed in known manner, each consisting of a cut-off block, its actuation block and its control block, which requires having all of the pieces in duplicate. Then the control handle of the upper switch is coupled to the two actuating blocks by lengthening the control shaft of said control block by a specific shaft extension, the attachment points of the connecting rods provided in the blocks actuation being modified on the control shaft. The handle can have three stable positions, a middle position "0" and two positions "I", "LT" on either side of the middle position, for example at - 65 ° and + 65 °. Inverter switches of this type allow only two switching combinations to be obtained: in the first combination, one of the switches is closed when the other is open and, in the middle position, both switches are open. In the second combination, one of the switches is closed when the other is open and, in the middle position, the two switches are closed simultaneously.
Pour obtenir un commutateur appelé "by-pass", utilisé pour isoler et court- circuiter une installation ou un circuit basse tension principalement lors d'interventions de maintenance, on superpose de manière connue trois interrupteurs standards dans le même sens, ce qui nécessite d'avoir la totalité des pièces en triple exemplaire. L'arbre de commande de la poignée doit être également complété avec une rallonge d'arbre spécifique.To obtain a switch called "by-pass", used to isolate and short-circuit a low-voltage installation or circuit mainly during maintenance operations, three standard switches are superimposed in a known manner in the same direction, which requires d '' have all parts in triplicate. The handle control shaft must also be completed with a specific shaft extension.
Pour une installation à six ou huit phases ou pôles, on accole de manière connue deux interrupteurs standards, ce qui nécessite d'avoir également la totalité des pièces en double exemplaire. Puis, on relie les poignées de commande par un dispositif d'accouplement mécanique généralement constitué d'une tringlerie complexe qui permet de transmettre le mouvement effectué sur une poignée à l'autre poignée.For an installation with six or eight phases or poles, two standard switches are joined in known manner, which also requires having all of the parts in duplicate. Then, the control handles are connected by a mechanical coupling device generally consisting of a complex linkage which makes it possible to transmit the movement carried out on one handle to the other handle.
Ces méthodes d'assemblage telles que pratiquées jusqu'à présent nécessitent un nombre important de pièces et de références standard, non obligatoirement nécessaires comme les blocs de commande en double ou en triple exemplaire, ce qui engendre un surcoût. De même, il faut des pièces et des références additionnelles spécifiques pour chaque type d'appareil de coupure réalisé. Ces pièces additionnelles engendrent un coût, un temps de montage et un encombrement supplémentaires. L'ensemble des pièces utiles représente par conséquent des coûts de fabrication, de stockage et de gestion non négligeables. Par ailleurs, le nombre de combinaisons de commutation est limité à deux.These assembly methods as practiced so far require a large number of parts and standard references, which are not necessarily necessary, such as control units in duplicate or in triplicate, which generates an additional cost. Likewise, specific parts and additional references are required for each type of switching device produced. These additional parts generate additional cost, assembly time and space. All of the useful parts therefore represent significant manufacturing, storage and management costs. Furthermore, the number of switching combinations is limited to two.
Par conséquent, le but de la présente invention est de pallier aux inconvénients mentionnés ci-dessus en réalisant un appareil de coupure, tel qu'un commutateur- inverseur, dans lequel le bloc d'actionnement et le bloc de commande ont fait l'objet d'une analyse de valeur et ont été optimisés pour réduire le nombre de pièces et de références nécessaires, faciliter le montage, permettre la réalisation simplement et à moindre coût d'un appareil du type "by-pass" ou d'un appareil à 6 ou 8 pôles. De plus, roptimisation desdits blocs permet d'offrir un nombre de combinaisons de commutation supérieur à deux. De ce fait, on obtient un appareil de coupure ayant un meilleur rapport qualité/prix avec de nouvelles fonctions. La réduction et la simplification du nombre de pièces et de références favorisent la réduction du prix de revient de l'ensemble et simplifie la gestion. A titre d'exemple, le nombre de pièces et de références peut être divisé par trois par rapport aux appareils de coupure standard.Consequently, the object of the present invention is to overcome the drawbacks mentioned above by providing a breaking device, such as a change-over switch, in which the actuation block and the control block have been the subject of a value analysis and have been optimized to reduce the number of parts and references required, facilitate assembly, allow the simple and inexpensive production of a device of the "bypass" type or of a device with 6 or 8 poles. In addition, the optimization of said blocks makes it possible to offer a number of combinations of switching greater than two. Therefore, we obtain a cutout device with a better quality / price ratio with new functions. The reduction and simplification of the number of parts and of references favor the reduction of the cost price of the whole and simplifies the management. For example, the number of parts and references can be divided by three compared to standard switching devices.
Ce but est atteint par un appareil de coupure tel que défini en préambule et caractérisé en ce que les blocs d'actionnement se superposent dos à dos et sont disposés entre les blocs de coupure inversés l'un par rapport à l'autre.This object is achieved by a switching device as defined in the preamble and characterized in that the actuating blocks are superimposed back to back and are arranged between the switching blocks inverted with respect to each other.

La présente invention et ses avantages apparaîtront mieux dans la description suivante d'un exemple de réalisation, en référence aux dessins annexés, dans lesquels :The present invention and its advantages will appear more clearly in the following description of an exemplary embodiment, with reference to the appended drawings, in which:

En référence à la figure 1, l'appareil de coupure 1 selon l'invention correspond à un commutateur-inverseur et comporte deux blocs de coupure 10, 20 superposés, un bloc supérieur 10 et un bloc inférieur 20, retournés l'un par rapport à l'autre. Il comporte également deux blocs d'actionnement 30, 40, un pour chaque bloc de coupure, disposés dos à dos et groupés dans un boîtier commun 50 monté entre les deux blocs de coupure 10, 20. Il comporte enfin un bloc de commande 60 disposé généralement à droite des blocs d'actionnement 30, 40 et pourvu d'un arbre de commande 64 pouvant recevoir une poignée de commande 61. Il s'agit d'une poignée à trois positions stables, une position médiane appelée "0" et deux positions appelées "I" et "II" à angle droit de part et d'autre de la position médiane, soit un angle de manoeuvre total de 180°. Chaque bloc de coupure 10, 20 comporte, de manière connue, au moins deux et, dans ce cas, quatre paires de bornes de connexion 11, 21 destinées à être raccordées aux conducteurs électriques d'une installation, dans ce cas, tétrapolaire, soit trois phases et un neutre. Egalement de manière connue, chaque bloc de coupure 10, 20 comporte autant de paires de contacts fixes que de paires de bornes de connexion et autant de contacts mobiles que de paires de contacts fixes. Les contacts mobiles sont montés sur un barreau mobile agencé pour coulisser en translation entre deux positions stables : une position fermée quand les contacts mobiles relient les paires de contacts fixes correspondantes et que la liaison électrique est assurée, et une position ouverte quand les contacts mobiles séparent les paires de contacts fixes correspondantes et que la liaison électrique est interrompue. Le barreau mobile de chaque bloc de coupure 10, 20 est actionné par son bloc d'actionnementWith reference to FIG. 1, the cut-off device 1 according to the invention corresponds to a change-over switch and comprises two cut-off blocks 10, 20 superimposed, one upper block 10 and a lower block 20, returned relative to each other. It also comprises two actuation blocks 30, 40, one for each cut-off block, arranged back to back and grouped in a common box 50 mounted between the two cut-off blocks 10, 20. It finally comprises a control block 60 arranged generally to the right of the actuating blocks 30, 40 and provided with a control shaft 64 which can receive a control handle 61. It is a handle with three stable positions, a middle position called "0" and two positions called "I" and "II" at right angles on either side of the middle position, ie a total operating angle of 180 °. Each switching block 10, 20 comprises, in known manner, at least two and, in this case, four pairs of connection terminals 11, 21 intended to be connected to the electrical conductors of an installation, in this case, four-pole, or three phases and a neutral. Also in known manner, each breaking block 10, 20 comprises as many pairs of fixed contacts as pairs of connection terminals and as many movable contacts as pairs of fixed contacts. The movable contacts are mounted on a movable bar arranged to slide in translation between two stable positions: a closed position when the movable contacts connect the pairs of corresponding fixed contacts and that the electrical connection is ensured, and an open position when the movable contacts separate the corresponding pairs of fixed contacts and that the electrical connection is interrupted. The movable bar of each cut-off block 10, 20 is actuated by its actuation block
30, 40, lequel est commandé par le bloc de commande 60. Ce bloc de commande 60 est fermé dans sa partie haute par une plaque appelée "plastron" 62 et peut être ouvert dans sa partie basse. H présente une hauteur équivalente à celle du bloc de coupure supérieur 10 et des blocs d'actionnement 30, 40. Il n'a en effet pas besoin de se prolonger au-delà. Les blocs de coupure 10, 20 et d'actionnement 30, 40 sont emboîtés les uns dans les autres au moyen de profils complémentaires et sont maintenus par des vis de fixation 12 visibles dans la figure 1 sur la face supérieure du bloc de coupure supérieur 10.30, 40, which is controlled by the control block 60. This control block 60 is closed in its upper part by a plate called "faceplate" 62 and can be opened in its lower part. H has a height equivalent to that of the upper cut-off block 10 and of the actuating blocks 30, 40. It does not in fact need to extend beyond. The cut-off blocks 10, 20 and of the actuation blocks 30, 40 are fitted into each other by means of complementary profiles and are held by fixing screws 12 visible in FIG. 1 on the upper face of the upper cut-off block 10 .
En référence à la figure 2, l'appareil de coupure 1 selon l'invention est représenté partiellement et en vue éclatée. La poignée de commande et le bloc de coupure inférieur ont été supprimés. Le plastron 62 et le bloc de coupure supérieur 10 ont été soulevés pour montrer l'intérieur du bloc d'actionnement supérieur 30, l'intérieur du bloc de commande 60 et le dessous du bloc de coupure supérieur 10 avec son barreau mobile 13. Dans cette réalisation, les blocs d'actionnement 30, 40 sont groupés dans le boîtier commun 50 pourvu de parois latérales 51 et d'une paroi médiane 52 séparant le boîtier 50 en deux parties égales dans le sens de sa hauteur, cette paroi médiane 52 constituant le fond de chaque bloc d'actionnement 30, 40. Comme on l'aperçoit sur cette figure, le boîtier commun 50 est réalisé d'un seul tenant avec le corps 63 du bloc de commande 60 pour simplifier leur fabrication et leur assemblage.Referring to Figure 2, the switching device 1 according to the invention is shown partially and in exploded view. The control handle and lower cutout block have been removed. The front plate 62 and the upper cut-off block 10 have been raised to show the inside of the upper actuation block 30, the inside of the control block 60 and the underside of the upper cut-off block 10 with its movable bar 13. In this embodiment, the actuating blocks 30, 40 are grouped in the common housing 50 provided with side walls 51 and a central wall 52 separating the housing 50 in two equal parts in the direction of its height, this central wall 52 constituting the bottom of each actuating block 30, 40. As we seen in this figure, the common housing 50 is made in one piece with the body 63 of the control unit 60 to simplify their manufacture and assembly.
Bien entendu, il est également possible de réaliser ce boîtier commun 50 en deux boîtiers séparés, identiques et emboîtables, un pour chaque bloc d'actionnement 30, 40. Cette réalisation est avantageuse car elle permet de fabriquer des interrupteurs simples avec le même boîtier. Le bloc de commande 60 comporte un arbre de commande 64 guidé en rotation dans le corps 63, cet arbre étant relié à la poignée de commande 61 par accouplement carré 65. Les blocs d'actionnement 30, 40 sont identiques mais inversés l'un par rapport à l'autre puisqu'ils sont placés dos à dos de part et d'autre de la paroi médiane 52 du boîtier commun 50. Les mêmes pièces porteront la même référence. Chaque bloc d'actionnement 30, 40 comporte une bielle 31 dont une première extrémité est couplée à l'arbre de commande 64 et une biellette d'entraînement 32 montée pivotante autour d'un axe central 33 fixe par rapport au boîtier 50. Ladite biellette 32 est couplée d'une part à la seconde extrémité de la bielle 31 et d'autre part au barreau mobile 13 du bloc de coupure correspondant 10, 20. Chaque bloc d'actionnement 30, 40 comporte également un dispositif d'accumulation d'énergie sous la forme d'un ressort 34, constitué plus précisément d'un ressort de torsion, pourvu de deux extrémités libres 35, 36. l'une 35 solidaire du boîtier 50 et l'autre 36 solidaire de la biellette 32. Ce ressort de torsion 34, permettant l'action brusque du mécanisme, accélère la commutation du barreau mobile 13 et par conséquent la commutation des contacts mobiles correspondants, c'est-à-dire le passage de la position ouverte à la position fermée et inversement. La liaison entre la bielle 31 et la biellette 32 s'effectue autour d'un premier tourillon 37 guidé dans une première rainure 38 en arc de cercle, prévue dans le boîtier 50 et s' étendant sur un secteur angulaire légèrement inférieur à 180°. dont le centre est confondu avec l'axe de pivotement 33 de la biellette 32. Un second tourillon 39 est prévu sur la biellette 32, diamétralement opposé au premier 37, et agencé pour coulisser dans une seconde rainure 41 identique, de même centre et symétrique. La liaison entre la biellette 32 et le barreau mobile 13 du bloc de coupure correspondant 10, 20 s'effectue par un tenon 42 solidaire de la biellette 32 et logé dans un évidement 14 ménagé dans le barreau 13. Cet évidement est délimité par deux butées 15, 16 permettant un déplacement en translation du tenon 42 relatif par rapport au barreau 13. Ce tenon 42 est sollicité par le ressort 34, son extrémité Ubre correspondante 36 étant logée dans un orifice traversant 43 prévu dans ledit tenon 42. Bien entendu, d'autres moyens de fixation appropriés peuvent être envisagés. Toutes les pièces composant un bloc d'actionnement 30, 40, à savoir la bielle 31, la biellette d'entraînement 32 et le ressort 34, sont assemblées par emboîtement et sont de ce fait facilement démontables. Ceci permet de changer leurs positions respectives dans un même bloc d'actionnement 30, 40 et d'un bloc à l'autre. Les différentes configurations obtenues permettent de réaliser différentes combinaisons de commutation entre les deux blocs de coupure 10, 20. Par exemple, la biellette 32 peut être couplée à la bielle 31 à son extrémité portant le tenon 42. De même, la biellette 32 peut être positionnée dans l'autre sens, la position du ressort étant également modifiée. Ces différentes configurations sont détaillées ci- après.Of course, it is also possible to produce this common housing 50 in two separate, identical and nestable housings, one for each actuating block 30, 40. This embodiment is advantageous because it makes it possible to manufacture simple switches with the same housing. The control block 60 comprises a control shaft 64 guided in rotation in the body 63, this shaft being connected to the control handle 61 by square coupling 65. The actuation blocks 30, 40 are identical but reversed one by relative to each other since they are placed back to back on either side of the middle wall 52 of the common housing 50. The same parts will have the same reference. Each actuating block 30, 40 comprises a connecting rod 31 of which a first end is coupled to the control shaft 64 and a drive rod 32 pivotally mounted around a central axis 33 fixed relative to the housing 50. Said rod 32 is coupled on the one hand to the second end of the connecting rod 31 and on the other hand to the movable bar 13 of the corresponding cutting block 10, 20. Each actuating block 30, 40 also comprises a device for accumulating energy in the form of a spring 34, more precisely consisting of a torsion spring, provided with two free ends 35, 36. one 35 secured to the housing 50 and the other 36 secured to the link 32. This spring torsion 34, allowing the sudden action of the mechanism, accelerates the switching of the movable bar 13 and therefore the switching of the corresponding movable contacts, that is to say the passage from the open position to the closed position and vice versa. The connection between the connecting rod 31 and the connecting rod 32 takes place around a first pin 37 guided in a first groove 38 in an arc of a circle, provided in the housing 50 and extending over an angular sector slightly less than 180 °. the center of which coincides with the pivot axis 33 of the link 32. A second pin 39 is provided on the link 32, diametrically opposite the first 37, and arranged to slide in a second identical groove 41, with the same center and symmetrical . The connection between the link 32 and the movable bar 13 of the corresponding cutting block 10, 20 is effected by a pin 42 secured to the link 32 and housed in a recess 14 formed in the bar 13. This recess is delimited by two stops 15, 16 allowing a displacement in translation of the pin 42 relative to the bar 13. This pin 42 is biased by the spring 34, its corresponding Ubre end 36 being housed in a through hole 43 provided in said tenon 42. Of course, other suitable fixing means can be envisaged. All the parts making up an actuating block 30, 40, namely the connecting rod 31, the driving rod 32 and the spring 34, are assembled by interlocking and are therefore easily removable. This makes it possible to change their respective positions in the same actuation block 30, 40 and from one block to another. The different configurations obtained make it possible to achieve different switching combinations between the two cut-off blocks 10, 20. For example, the link 32 can be coupled to the link 31 at its end carrying the stud 42. Similarly, the link 32 can be positioned in the opposite direction, the position of the spring also being modified. These different configurations are detailed below.
La figure 3 illustre partiellement l'appareil 1 de la figure 2 et notamment le bloc de coupure inférieur 20 avec son barreau mobile 13, l'arbre de commande 64 et les deux blocs d'actionnement 30, 40 sans les ressorts ni le boîtier commun 50. On aperçoit clairement la liaison des bielles 31 sur l'arbre de commande 64. Cet arbre de commande 64 comporte deux disques 66, 67 parallèles entre eux et perpendiculaires à l'axe de rotation Y dudit arbre, chaque disque étant pourvu d'un pivot 68, 69 pour chaque bielle 31. Les deux pivots 68, 69 ne se superposent pas directement, ils sont décalés l'un par rapport à l'autre. Leur position respective sur leur disque 66, 67 peut être modifiée comme on le verra plus loin. L'extrémité correspondante de chaque bielle 31 comporte un logement oblong 44 apte à recevoir son pivot 68, 69, ce qui laisse à la bielle 31 un certain jeu dans son déplacement par rapport à l'arbre de commande 64, dont l'intérêt est expliqué plus loin. Cette figure illustre les bielles 31 et les biellettes d'entraînement 32 des deux blocs d'actionnement 30, 40 dans la même configuration mais retournée l'une par rapport à l'autre. Le tenon 42 de la biellette 32 du bloc d'actionnement inférieur 40 est logé dans l'évidement 14 du barreau mobile 13 du bloc de coupure inférieur 20. On remarque également les tourillons 37 de liaison des biellettes 32 avec les bielles 31.Figure 3 partially illustrates the apparatus 1 of Figure 2 and in particular the lower cutout block 20 with its movable bar 13, the control shaft 64 and the two actuation blocks 30, 40 without the springs or the common housing 50. We can clearly see the connection of the connecting rods 31 on the control shaft 64. This control shaft 64 comprises two discs 66, 67 parallel to each other and perpendicular to the axis of rotation Y of said shaft, each disc being provided with a pivot 68, 69 for each connecting rod 31. The two pivots 68, 69 are not directly superimposed, they are offset relative to each other. Their respective position on their disc 66, 67 can be modified as will be seen below. The corresponding end of each connecting rod 31 has an oblong housing 44 capable of receiving its pivot 68, 69, which leaves the connecting rod 31 a certain play in its movement relative to the control shaft 64, the advantage of which is explained further. This figure illustrates the connecting rods 31 and the drive rods 32 of the two actuating blocks 30, 40 in the same configuration but turned one relative to the other. The pin 42 of the link 32 of the lower actuation block 40 is housed in the recess 14 of the movable bar 13 of the lower cut-out block 20. The pins 37 for connecting the link 32 with the connecting rods 31 are also noted.
En référence également à la figure 4, l'arbre de commande 64 comporte de haut en bas:With reference also to FIG. 4, the control shaft 64 comprises from top to bottom:
- une section carrée creuse 65 pour recevoir la poignée disposée à l'extérieur du plastron 62, laquelle est maintenue par une goupille dans un trou correspondant 65', - une section circulaire 70 pour guider en rotation l'arbre 64 dans le plastron 62,a hollow square section 65 for receiving the handle disposed outside the faceplate 62, which is held by a pin in a corresponding hole 65 ′, a circular section 70 for guiding the shaft 64 in rotation in the faceplate 62,
- des ailettes ou cames 71 décalées angulairement l'une par rapport à l'autre,- fins or cams 71 angularly offset with respect to each other,
- les deux disques 66, 67 portant les pivots 68, 69 de liaison des bielles 31 et reliés par un fût 72 partiellement circulaire, - une section circulaire 73 pour guider en rotation l'arbre 64 dans le corps 63 du bloc de commande 60, etthe two discs 66, 67 carrying the pivots 68, 69 for connecting the connecting rods 31 and connected by a partially circular barrel 72, - a circular section 73 for guiding the shaft 64 in rotation in the body 63 of the control unit 60, and

Les cames 71 sont agencées pour commander des contacts auxiliaires 80 en fonction de la position de l'arbre de commande 64. Un ou plusieurs contacts auxiliaires 80 à ouverture ou à fermeture sont généralement associés à chaque bloc de coupure pour permettre la transmission via une liaison électrique d'une information relative à la position de ces blocs de coupure 10, 20 vers un ou plusieurs circuits de commande ou de surveillance (relais auxiliaires, automates, alarmes, etc.). En particulier, les contacts auxiliaires assurent une information de précoupure vers les équipements branchés en aval pour les déclencher avant le déclenchement du ou des blocs de coupure concernés. Ces contacts auxiliaires 80 sont de type standard et comportent un piston d'actionnement 81 commandé directement par les cames 71 prévues sur l'arbre de commande 64. Au besoin, des contacts auxiliaires complémentaires 82 peuvent être ajoutés en regard du fût 72. Dans ce cas, ces contacts auxiliaires 82 sont commandés par un dispositif à palette 83 actionné par ledit fût 72. Tous ces contacts auxiliaires 80, 82 sont facilement logés et fixés par des vis dans le bloc de commande 60 au moyen des rainures longitudinales 75 et de supports 76 prévus dans le corps 63 de ce bloc, visibles dans la figure 2.The cams 71 are arranged to control auxiliary contacts 80 as a function of the position of the control shaft 64. One or more auxiliary contacts 80 with opening or closing are generally associated with each cut-off block to allow transmission via a link electrical information relating to the position of these cut-off blocks 10, 20 to one or more control or monitoring circuits (auxiliary relays, PLCs, alarms, etc.). In particular, the auxiliary contacts provide precut information to the equipment connected downstream to trigger it before the triggering of the cut-off block (s) concerned. These auxiliary contacts 80 are of the standard type and include an actuating piston 81 controlled directly by the cams 71 provided on the control shaft 64. If necessary, additional auxiliary contacts 82 can be added opposite the barrel 72. In this In this case, these auxiliary contacts 82 are controlled by a paddle device 83 actuated by said barrel 72. All of these auxiliary contacts 80, 82 are easily housed and fixed by screws in the control unit 60 by means of the longitudinal grooves 75 and supports 76 provided in the body 63 of this block, visible in FIG. 2.
Les figures 5 à 7 illustrent plus en détail les blocs d'actionnement 30, 40 et le bloc de commande 60. La figure 5 est une vue de dessus du bloc d'actionnement supérieur 30 dans laquelle on retrouve l'arbre de commande 64, la bielle 31, sa liaison pivot 68 représentée en pointillés avec l'arbre de commande 64, la biellette d'entraînement 32, son axe de pivotement fixe 33, ses deux tourillons 37, 39 guidés dans les rainures correspondantes 38, 41, le tenon d'actionnement 42 du barreau mobile 13 et le ressort 34. La figure 6 est une section transversale de la figure 5 montrant les blocs d'actionnement supérieur 30 et inférieur 40, le boîtier commun 50 et l'arbre de commande 64. H apparaît clairement sur cette figure que les pièces composant chaque bloc d'actionnement 30, 40 sont disposées de manière inverse pour correspondre à leur bloc de coupure 10, 20 également inversés. La figure 7 illustre le bloc d'actionnement 30 de la figure 5, l'arbre de commande 64 ayant tourné d'environ 45° dans le sens inverse des aiguilles d'une montre suivant la flèche F.FIGS. 5 to 7 illustrate in greater detail the actuating blocks 30, 40 and the control block 60. FIG. 5 is a top view of the upper actuating block 30 in which the control shaft 64 is found, the rod 31, its pivot link 68 shown in dotted lines with the control shaft 64, the drive rod 32, its fixed pivot axis 33, its two pins 37, 39 guided in the corresponding grooves 38, 41, the tenon actuator 42 of the movable bar 13 and the spring 34. FIG. 6 is a cross section of FIG. 5 showing the upper 30 and lower 40 actuation blocks, the common housing 50 and the control shaft 64. H appears clearly in this figure that the parts making up each actuating block 30, 40 are arranged inversely to correspond to their cut-off block 10, 20 also inverted. FIG. 7 illustrates the actuating block 30 of FIG. 5, the control shaft 64 having rotated approximately 45 ° in the anticlockwise direction according to the arrow F.
Le fonctionnement des blocs d'actionnement 30, 40 est à présent décrit en référence à cette figure 7.The operation of the actuating blocks 30, 40 is now described with reference to this FIG. 7.
Pour passer d'une position stable à la suivante, l'arbre de commande 64, et donc la poignée 61, doivent être tournés de 90°, soit une rotation de 180° pour aller de la position "I" à la position "H" en passant par la position intermédiaire "0". Le bloc de coupure supérieur 10 s'enclenche en position fermée par une rotation de l'arbre de commande de 90° dans le sens inverse des aiguilles d'une montre (flèche F) alors que le bloc de coupure inférieur 20 s'enclenche en position fermée par une rotation de l'arbre de commande de 90° dans le sens des aiguilles d'une montre (flèche G). Lors de ces rotations, les mouvements suivants s'effectuent conjointement :To move from one stable position to the next, the control shaft 64, and therefore the handle 61, must be rotated 90 °, ie a rotation of 180 ° to go from position "I" to position "H "passing through the intermediate position" 0 ". The upper cut-off block 10 engages in the closed position by rotating the control shaft 90 ° counterclockwise (arrow F) while the lower cut-off block 20 snaps into place. closed position by rotating the control shaft 90 ° clockwise (arrow G). During these rotations, the following movements are carried out jointly:
- translation de la bielle 31,- translation of the connecting rod 31,
- rotation de la biellette d'entraînement 32 autour de son axe 33,- rotation of the drive rod 32 around its axis 33,
- contrainte sur le ressort 34 et accumulation d'énergie puis, passé l'axe central Z passant par le centre des rainures 38, 41 et l'axe de pivotement 33 de la biellette 32, restitution de l'énergie accumulée générant un actionnement brusque de la biellette 32,- stress on the spring 34 and accumulation of energy then, past the central axis Z passing through the center of the grooves 38, 41 and the pivot axis 33 of the link 32, restitution of the accumulated energy generating a sudden actuation of the link 32,
- translation du barreau mobile 13 du bloc de coupure 10, 20 correspondant grâce au tenon 42 de la biellette d'entraînement 32 logé dans l'évidement 14 dudit barreau.- Translation of the movable bar 13 of the cut-off block 10, 20 corresponding with the pin 42 of the drive rod 32 housed in the recess 14 of said bar.
Un jeu de fonctionnement entre le barreau mobile 13 et le tenon 42 grâce à l'intervalle séparant les butées 15, 16 prévues sur ledit barreau, ainsi qu'entre la bielle 31 et l'arbre de commande 64 grâce au logement oblong 44 prévu dans ladite bielle, permet l' actionnement brusque des barreaux mobiles 13. Cet actionnement brusque assure l'enclenchement et le déclenchement des blocs de coupure 10, 20 en un laps de temps très court, indépendamment de la vitesse de manoeuvre de la poignée 61. Le logement oblong 44 prévu sur les bielles 31 assure également le débrayage momentané du bloc d'actionnement correspondant pendant la manoeuvre de l'autre bloc d'actionnement. Pour commuter les blocs de coupure 10, 20 en sens inverse, il suffit de manoeuvrer l'arbre de commande 64, c'est-à-dire la poignée 61, en sens inverse provoquant les mouvements inverses de la bielle 31, de la biellette 32 et du ressort 34.An operating clearance between the movable bar 13 and the tenon 42 thanks to the interval separating the stops 15, 16 provided on said bar, as well as between the connecting rod 31 and the control shaft 64 thanks to the oblong housing 44 provided in said connecting rod allows the abrupt actuation of the movable bars 13. This abrupt actuation ensures the engagement and tripping of the cut-off blocks 10, 20 in a very short period of time, regardless of the speed of operation of the handle 61. The oblong housing 44 provided on the connecting rods 31 also ensures the momentary disengagement of the corresponding actuation block during the operation of the other actuation block. To switch the cut-off blocks 10, 20 in the opposite direction, it suffices to maneuver the control shaft 64, that is to say the handle 61, in the opposite direction causing the reverse movements of the connecting rod 31, of the connecting rod 32 and spring 34.
Les figures 8 à 12 illustrent les différentes configurations possibles des blocs d'actionnement 30, 40 et par conséquent les différentes combinaisons de commutation obtenues pour chaque configuration avec l'appareil 1 selon l'invention. Les figures portant l'indice A représentent le bloc d'actionnement supérieur 30 en vue de dessus et les figures portant l'indice B représentent le bloc d'actionnement inférieur 40 en vue de dessous. Pour simplifier l'explication qui suit, les positions de commutation des blocs de coupure 10, 20 sont symbolisées par "1" pour la position fermée et par "0" pour la position ouverte. De même, les positions de la poignée 61 ou de l'arbre de commande 64 sont symbolisées par "0" pour la position médiane, par "I" pour la position à 90° dans le sens inverse des aiguilles d'une montre (flèche F) par rapport "0" et par "LT" pour la position à 90° dans le sens des aiguilles d'une montre (flèche G) par rapport àFigures 8 to 12 illustrate the different possible configurations of the actuating blocks 30, 40 and therefore the different switching combinations obtained for each configuration with the device 1 according to the invention. The figures bearing the index A represent the upper actuating block 30 seen from above and the figures bearing the index B represent the lower actuating block 40 seen from below. To simplify the explanation which follows, the switching positions of the cut-off blocks 10, 20 are symbolized by "1" for the closed position and by "0" for the open position. Likewise, the positions of the handle 61 or of the control shaft 64 are symbolized by "0" for the middle position, by "I" for the 90 ° position in the anticlockwise direction (arrow F) with respect to "0" and with "LT" for the 90 ° position clockwise (arrow G) with respect to
"0"."0".
Comme il est dit précédemment, la position respective des bielles 31, biellettes 32 et ressorts 34 peut varier. De même, la position des pivots 68, 69 peut être modifiée. Il est précisé que ces modifications sont apportées en usine lors du montage des appareils et selon les besoins spécifiques du client. Dans les figures 8 à 10, toutes les pièces sont identiques d'une configuration à l'autre et les pivots 68, 69 sont disposés symétriquement par rapport à l'axe longitudinal X. Dans ces figures, la configuration des blocs d'actionnement 30, 40 représentés correspond à la position médiane "0" de la poignée 61.As mentioned above, the respective position of the connecting rods 31, connecting rods 32 and springs 34 may vary. Likewise, the position of the pivots 68, 69 can be modified. It is specified that these modifications are made in the factory during the assembly of the devices and according to the specific needs of the customer. In FIGS. 8 to 10, all the parts are identical from one configuration to another and the pivots 68, 69 are arranged symmetrically with respect to the longitudinal axis X. In these figures, the configuration of the actuating blocks 30 , 40 represented corresponds to the middle position "0" of the handle 61.
Dans les figures 8A et 8B, les bielles 31, biellettes 32 et ressort 34 sont disposés comme dans les figures précédentes. La liaison entre la bielle 31 et la biellette 32 de chaque bloc d'actionnement 30, 40 s'effectue sur le premier tourillon 37 logé dans la première rainure 38 et le ressort 34 est sensiblement dans l'axe central Z. On obtient la combinaison de commutation suivante :In FIGS. 8A and 8B, the connecting rods 31, connecting rods 32 and spring 34 are arranged as in the preceding figures. The connection between the connecting rod 31 and the connecting rod 32 of each actuating block 30, 40 takes place on the first pin 37 housed in the first groove 38 and the spring 34 is substantially in the central axis Z. The combination is obtained following switching:

Cette combinaison permet d'obtenir un commutateur-inverseur à trois positions stables avec, en position intermédiaire, les deux blocs de coupure 10, 20 en position ouverte.This combination makes it possible to obtain a reversing switch with three stable positions with, in the intermediate position, the two cut-off blocks 10, 20 in the open position.
Dans les figures 9 A et 9B, la haison entre la bielle 31 et la biellette 32 de chaque bloc d'actionnement 30, 40 s'effectue sur le second tourillon 39 logé dans la seconde rainure 41 et le ressort 34 est décentré par rapport à l'axe central Z. On obtient la combinaison de commutation suivante :In FIGS. 9 A and 9B, the hedge between the connecting rod 31 and the connecting rod 32 of each actuating block 30, 40 is carried out on the second pin 39 housed in the second groove 41 and the spring 34 is off-center with respect to the central axis Z. The following switching combination is obtained:

Dans les figures 10A et 10B. la haison entre la bielle 31 et la biellette 32 du bloc d'actionnement supérieur 30 s'effectue sur le second tourillon 39 logé dans la seconde rainure 41 et le ressort 34 est décentré par rapport à l'axe central Z. La haison entre la bielle 31 et la biellette 32 du bloc d'actionnement inférieur 40 s'effectue sur le premier tourillon 37 logé dans la première rainure 38 et le ressort 34 est centré sur l'axe central Z. On obtient la combinaison de commutation suivante :In Figures 10A and 10B. the hedge between the connecting rod 31 and the connecting rod 32 of the upper actuating block 30 is carried out on the second pin 39 housed in the second groove 41 and the spring 34 is off-center with respect to the central axis Z. The hedge between the connecting rod 31 and the connecting rod 32 of the lower actuating block 40 takes place on the first pin 37 housed in the first groove 38 and the spring 34 is centered on the central axis Z. The following switching combination is obtained:

Cette combinaison permet d'obtenir un commutateur à superposition à trois positions stables avec, en position "II", la superposition des deux blocs de coupure 10, 20 en position fermée.
Figure imgf000014_0003
This combination makes it possible to obtain a superposition switch with three stable positions with, in position "II", the superposition of the two cut-off blocks 10, 20 in the closed position.
Dans les figures 11 et 12, les bielles 31 sont légèrement plus courtes que celles utihsées dans les figures précédentes et les pivots 68, 69 sur l'arbre de commande 64 sont diamétralement opposés. C'est la position du pivot 68 correspondant au bloc d'actionnement supérieur 30 qui est modifiée. Dans ce cas, la position médiane "0" de la poignée 61 n'existe plus, les deux positions "I" et "II" étant obtenues par une rotation de 90°.In FIGS. 11 and 12, the connecting rods 31 are slightly shorter than those used in the preceding figures and the pivots 68, 69 on the control shaft 64 are diametrically opposite. It is the position of the pivot 68 corresponding to the upper actuating block 30 which is modified. In this case, the middle position "0" of the handle 61 no longer exists, the two positions "I" and "II" being obtained by a rotation of 90 °.
Dans les figures 11A et 11B, la haison entre la bielle 31 et la biellette 32 du bloc d'actionnement supérieur 30 s'effectue sur le second tourillon 39 logé dans la seconde rainure 41, le ressort 34 étant dans l'axe central Z. La haison entre la bielle 31 et la biellette 32 du bloc d'actionnement inférieur 40 s'effectue sur le premier tourillon 37 logé dans la première rainure 38, le ressort étant aussi dans l'axe central Z. On obtient la combinaison suivante :In FIGS. 11A and 11B, the hedge between the connecting rod 31 and the connecting rod 32 of the upper actuating block 30 is carried out on the second pin 39 housed in the second groove 41, the spring 34 being in the central axis Z. The hedge between the connecting rod 31 and the connecting rod 32 of the lower actuating block 40 is carried out on the first pin 37 housed in the first groove 38, the spring also being in the central axis Z.

Dans les figures 12 A et 12B, la haison entre la bielle 31 et la biellette 32 du bloc d'actionnement supérieur 30 s'effectue sur le second tourillon 39 logé dans la seconde rainure 41, le ressort 34 étant dans l'axe central Z.

The combination is obtained following switching:
Figure imgf000016_0001
Cette combinaison permet d'obtenir un commutateur-inverseur à deux positions stables.This combination makes it possible to obtain a reversing switch with two stable positions.
En plus des multiples combinaisons de commutation détaillées ci-dessus, la conception des blocs d'actionnement 30, 40 et du bloc de commande 60 autorise une grande flexibilité d'utilisation.In addition to the multiple switching combinations detailed above, the design of the actuating blocks 30, 40 and the control block 60 allows great flexibility of use.
Pour obtenir un interrupteur simple à trois ou quatre pôles, il suffit d'équiper uniquement le boîtier 50 du bloc d'actionnement correspondant au bloc de coupure.To obtain a simple three or four pole switch, it suffices to equip only the housing 50 with the actuation block corresponding to the cut-off block.
Pour réaliser un interrupteur à six ou huit pôles, on juxtapose deux interrupteurs simples à trois ou quatre pôles, tels que décrits ci-dessus. Dans ce cas, on utilise une bielle différente et spécifique pour commander simultanément les deux blocs de coupure juxtaposés et on modifie l'emplacement du pivot sur l'arbre de commande.To make a six or eight pole switch, two simple three or four pole switches are juxtaposed, as described above. In this case, a different and specific connecting rod is used to simultaneously control the two juxtaposed cut-off blocks and the location of the pivot on the control shaft is modified.
Pour réaliser un appareil de coupure de type "by-pass" associé à un commutateur- inverseur, on ajoute un interrupteur simple sous le bloc de coupure inférieur de l'appareil 1 selon l'invention. Dans ce cas, l'extrémité carrée 74 de l'arbre de commande 64 du bloc de commande 60 se loge directement dans l'extrémité supérieure de l'arbre de commande de cet interrupteur.To make a cut-out device of the "by-pass" type associated with a change-over switch, a simple switch is added under the lower cut-off block of the device 1 according to the invention. In this case, the square end 74 of the control shaft 64 of the control block 60 is housed directly in the upper end of the control shaft of this switch.
Pour réaliser un appareil tétrapolaire pour une installation comportant trois phases et un neutre, comme illustré par la figure 1, le boîtier commun 50 comportant les blocs d'actionnement 30, 40 peut être utilisé sans modification malgré la différence de longueur des blocs de coupure 10, 20. Un simple boîtier "entretoise" 55 peut être intercalé entre les deux blocs de coupure 10, 20 en prolongement du boîtier commun 50. Ce boîtier "entretoise" ne comporte aucun mécanisme d'actionnement étant donné que le contact mobile correspondant au neutre de chaque bloc de coupure 10, 20 est monté sur le barreau mobile, lequel est actionné par lesdits blocs d'actionnement 30, 40 comme décrit plus haut.To make a four-pole device for an installation comprising three phases and a neutral, as illustrated in FIG. 1, the common box 50 comprising the actuation blocks 30, 40 can be used without modification despite the difference in length of the cut-off blocks 10 , 20. A simple “spacer” box 55 can be interposed between the two cut-off blocks 10, 20 as an extension of the common box 50. This “spacer” box does not have any actuation mechanism since the movable contact corresponding to the neutral of each cut-off block 10, 20 is mounted on the movable bar, which is actuated by said actuating blocks 30, 40 as described above.
Bien entendu, toutes les combinaisons entre ces différents appareils sont envisageables. H apparaît clairement que l'appareil de coupure 1 selon l'invention atteint tous les buts mentionnés précédemment. La présente invention n'est bien entendu pas limitée aux exemples de reahsation décrits mais s'étend à toute modification et variante évidente pour un homme du métier. Of course, all combinations between these different devices are possible. It is clear that the switching device 1 according to the invention achieves all the goals mentioned above. The present invention is of course not limited to the examples of reahsation described but extends to any modification and variant obvious to a person skilled in the art.
